Enter your machine's PSI and GPM and get the orifice sizes, tip codes and a J-rod build that actually match it — plus surface-cleaner nozzle sizing. The exact tool inside Crewplate.
Loading the bench…
An undersized tip wastes your machine; an oversized one drops your pressure. This lab works the industry orifice chart backwards from your real numbers, builds a J-rod four tips at a time, and sizes surface-cleaner nozzles by bar count.
